EDWARD G. DONNELLY, OF HIGHLAND PARK, ILLINOIS.

HORSESHOE.

To all whom it may concern Be it known that I, EDWARD G. DONNELLY, formerly a subject of the Queen of Great Britain, but who has declared his intention of becoming a citizen of the United States, and a resident of the city of Highland Park, county of Lake, and State of Illinois, have invented certain. new and useful Improvements in Horseshoes, of which the following is a specification.

My invention relates to improvements in horse shoes, and has for its object the provision of an improved horse shoe and method of making the same.

The invention consists in the combinations and arrangements of parts, and the method of making the same hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which, n r

Figure l is a plan view of the strip from which the horse shoe is made illustrating the method of embedding the hardened steel pieces in the ends thereof, Fig. 2, a side view of one of the hardened pieces of steel, Fig.

3, an end view corresponding to Fig. 2, Fig. i, a side elevation of a completed shoe, Fig. 5, a section taken on substantially line w00 of Fig. 4-, Fig. 6, a side elevation of a modified form of heel calk, and Fig. 7 a bottom plan view of the calk shown in Fig. 6.

For carrying my invention into eiiect, I first provide a strip 1 of wrought iron and split the ends of the same, as indicated in Fig. 1. Cross-shaped pieces 2 of hardened steel substantially the length of the heel calks are placed in the splits formed in the ends of strip 1 and embedded therein by heating said ends and compressing them about said pieces. The pieces 2 have comparatively wide flanges 3 and narrower flanges 4 arranged at right angles thereto, the central portion being cylindrical in form to form reinforcing fillets 5 between the inner ends of flanges 3 and 4 as shown in Fig. 3. Flanges 4 are beveled at 6 as shown in Fig. 2 to facilitate insertion in the splits in the ends of strip 1. The strip 1 is then formed into the usual horse shoe form with the ends of the strip in the same plane as the body thereof. The blacksmith then bends the ends of the strip to form heel Specification of Letters Patent. Pat nted Sept 30, 1913 Application filed February 8, 1912.

calks 7 as is usual and provides any of the usual forms of toe calks 8 thereto, when the shoe is ready for application.

In use the hardened steel pieces 2 will prolong the life of'the heel calks of the shoe and owing to the factthat they are surrounded by softer metal and to the cross shape given them will normally project slightly from the bottom of the heel calks and thus provide an effective engagement with the ground to prevent slipping. By making the pieces 2 short and substantially equal to the length of the desired heel calks, a high grade steel may be employed, inasmuch as but little heating is required to embed the pieces and bend the heel calks, a high degree of temperature tending to draw the temper of the steel and thus impair its efficiency.

In Figs. 6 and 7 I have illustrated a construction in which the heel call: 7 is drawn out to a wedge point, which is sometimes desiralole.

While I have illustrated and described the preferred forms of construction for carrying my invention into effect, and the preferred method for making the shoe, these may be varied without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the exact details of construction set forth, or the eXact steps recommended, but desire to avail myself of such variations and modifications as fall within the scope of the appended claim.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

A horse shoe comprising a shoe proper provided with calks, each call; having an upwardly extending circular recess therein and two grooves narrower than the diameter of such circular recess extending from side to side of said calk and intersecting each other at said circular recess; and hard cores fitted in said recesses and grooves, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
